SIFTER Filed Oct. 5, 1939 Patented May 20, 1941 UNITED STATES PATE OFFICE parts to each other has usually been such that in imparting a sidewise swinging motion to bring about the desired sifting action causes the sifterbody to rock about the carrying handle as an axis with the result that the material being sifted is thrown outside the container intended to receive it, even when the handle is tightly gripped. That is to say, the place of connection of the handle with the device is such with reference to the body that in the imparted side to side movement the heaviest portion of the said body tends to set up a rocking movement aboutthe handle as an axis instead whereas the body should retain an upright position during such sidewise motion.

The purpose herein is to so mount the parts relatively that this upright position of the body shall be maintained without requiring undue gripping action on the handle, and that therefore the sifted material shall always fall within a limited area.

Besides the named object the invention lies in details of construction to be pointed out herein and for the subject of certain of the claims to follow.

That the structure and purpose may be fully understood the accompanyin drawing is provided which forms a part thereof.

Figure 1 is a plan of one form of the improved sifter;

Figure 2 is a side elevation of the same, parts being shown in section;

Figure 3 is a side elevation of another form of the sifter, parts being shown in section;

Figure 4 shows in perspective parts shown in Figure 3;

Figure 5 shows in perspective a seal for a part of the sifter as a modification of the form of device shown in the previously named figures, and

Figures 6 and '7 show in perspective, and on a larger scale, a housing shown in Figures 1, 2, 3 and 4.

The body of the sifter is indicated by the numeral I, the same having any usual sifting screen 2.

In the first four figures is shown a housing affixed to the inner side wall of the body I. As shown in Figures 6 and '7, particularly, this housing may be a stamping in which is a channel portion 3 having an extended wing 4 at each side thereof for convenience in soldering or otherwise securing the same to said wall of the body I. In Figures 1 and 2 a wire member or agitator 5 is shown to traverse the screen-bottom 2 and lie fiat thereupon. The wire is formed at right angles at 6 formin a shaft portion, which is enclosed in the channel portion 3, lying between the latter and the body wall. Further, the wire is provided with a bend l lying substantially parallel to the member 5 and extends through a slot 8 in the wall of said channel memher, the wire being again formed to have an upright portion 9, Figure 2 thence extending into a goose-neck Ill which extends over the wall of the body and terminates in a handle portion H which lies directly opposite the slot 8.

In Figures 3 and 4, however, the wire and its rake portion denoted by B and fi'irespectively has a goose-neck I0 terminating in a handle portion H which extends through a slot-opening I2 the body wall directly above the channel member. the handle extension close to the supporting point on the body is such that the weight of the latter is evenly balanced above and below said point and therefore where the sidewise shaking movement imparted to the body will in no way cause it to tip or roll about the handle. It may be stated that in assembling the parts the wire may be formed complete after which the channel member 3, 4 can be slipped thereupon, the whole being then placed in position in the body i and the said channel member secured in place.

Preferably, the member last mentioned has the slotopening 8 in its side so that the material to be sifted may readily work out through such opening as it could not readily do if the wire entered at the top thereof. In this connection, however, Figure 5 shows a form wherein the wire 6 I0 may extend into the top of the channel member 3, while a closure 3 will prevent the material entering.

In Figure 3 where the slot opening I2 is in the body-wall a closure I0 carried by the handle portion Il' prevents material flowing too readily therethrough. a

While the structure has been described some- In either form, it will be observed,

what in detail it is understood that changes may be made such as will fairly fall within the meaning of the claims herein.

I claim:

1. In a sifter, the combination with a sifter body having a sitter bottom, and side Walls upstanding above said bottom, of an upstanding channel portion parallel to and erecting at the inner surface of the side wall of the body and extending substantially to mid-height of the side wall and spaced at its lower end from said bottom, a wall of said channel portion being slightly and uniformly spaced from said side wall of the body and having an opening therein near the top of the channel portion, an agitator element having a portion traversing over and close to said bottom and also having an upstanding shaft, the lower portion of said shaft being enclosed by said channel portion and also having an angular bend thereon providing a small portion extending substantially horizontal, said bend coinciding with the location of said opening and extending through said opening with a small clearance therewith and into the space of the sitter body, an equal and reverse bend in said shaft beyond said horizontal portion and a shaft extension beyond said bend, said extension arising to and extending over the top edge of the sifter body and thence downwardly outside the same and terminating in a handle portion lying substantially opposite the position of the named opening of said channel portion.

2. The invention according to claim 1 and wherein the named Wall of the channel portion spaced from the wall of the body closes the channel above the named lower portion of the agitator shaft.
